This library contains g-functions (thermal response functions) for standard, regularly spaced vertical borehole ground heat exchangers. In total, it contains 34, 321 configurations. To permit interpolation, each configuration has g-functions for heights of 24, 48, 96, 192, and 384 m. All the g-functions were calculated with burial depths of 2m, and borehole diameters of 15 to 17.5 cm, depending on height. In configurations with uniform spacing, the spacing between the boreholes is set to 5m, though it can be scaled to other horizontal spacings.

The information center contains various information and documents, such as congressional testimony, recovery act, educational materials, reporting, library, etc.
The Regulatory and Permitting Information Desktop (RAPID) Toolkit combines the former Geothermal Regulatory Roadmap, National Environmental Policy Act (NEPA) Database, and other resources into a Web-based tool that gives the regulatory and utility-scale geothermal developer communities rapid and easy access to permitting information. RAPID currently comprises five tools: Permitting Atlas, Regulatory Roadmap, Resource Library, NEPA Database, and Best Practices. Because of the huge amount of information involved, RAPID was developed in a wiki platform to allow industry and regulatory agencies to maintain the content in the future so that it continues to provide relevant and accurate information to users. The content was expanded to include regulatory requirements for utility-scale solar, hydropower, and bulk transmission development projects. Going forward, development of the RAPID Toolkit will focus on expanding the capabilities of current tools, developing additional tools, including additional technologies, and continuing to increase stakeholder involvement.
National Energy Technology Laboratory’s (NETL) GEO Water Energy Link Library, geoWELL, is a map-based application that provides quick access to the primary on-line sources of subsurface geologic and wellbore (oil, gas, and underground injection) information for appropriate U.S. state, tribal and federal agencies.
